In graphite, each carbon atom is bonded to three other carbon atoms
General KnowledgeChemistry
- Aforming a three-dimensional structure.
- Bin the same plane giving a hexagonal array.
- Cin the same plane giving a square array.
- Din the same plane giving a pentagonal array.
Explanation
In graphite, each carbon atom bonds covalently to three others in the same plane, forming flat hexagonal rings in a honeycomb arrangement; the layers are held by weak van der Waals forces. It is not a pentagonal, circular or linear arrangement. Hence hexagonal.
